Acetic Acid, 2-Ethylhexyl Ester; Exemption From the Requirement 
of a Tolerance

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes an exemption from the requirement 
of a tolerance for residues of acetic acid, 2-ethylhexyl ester (CAS 
Reg. No. 103-09-3) when used as an inert ingredient (solvent/cosolvent) 
at a concentration not to exceed 50% in pesticide formulations applied 
to growing crops. SciReg, Inc., on behalf of Solvay USA Inc., submitted 
a petition to EPA under the Federal Food, Drug, and Cosmetic Act 
(FFDCA), requesting establishment of an exemption from the requirement 
of a tolerance. This regulation eliminates the need to establish a 
maximum permissible level for residues of acetic acid, 2-ethylhexyl 
ester, when used in accordance with the terms of the exemption.

DATES: This regulation is effective November 8, 2022. Objections and 
requests for hearings must be received on or before January 9, 2023, 
and must be filed in accordance with the instructions provided in 40 
CFR part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Petition for Exemption

    In the Federal Register of June 8, 2017 (82 FR 26641) (FRL-9961-
14), EPA issued a document pursuant to FFDCA section 408, 21 U.S.C. 
346a, announcing the filing of a pesticide petition (PP IN-11014) by 
SciReg, Inc., 12733 Director's Loop, Woodbridge, VA 22192 on behalf of 
Solvay USA Inc., 504 Carnegie Center, Princeton, NJ 08540. The petition 
requested that 40 CFR 180.920 be amended by establishing an exemption 
from the requirement of a tolerance for residues of acetic acid, 2-
ethylhexyl ester (CAS Reg. No. 103-09-3) when used as an inert 
ingredient (solvent/co-solvent) in pesticide formulations at no more 
than 50% when applied to growing crops only under 40 CFR 180.920. That 
document referenced a summary of the petition prepared by SciReg, Inc., 
on behalf of Solvay USA Inc., the petitioner, which is available in the 
docket, https://www.regulations.gov. There were no comments received in 
response to the notice of filing.

III. Inert Ingredient Definition

    Inert ingredients are all ingredients that are not active 
ingredients as defined in 40 CFR 153.125 and include, but are not 
limited to, the following types of ingredients (except when they have a 
pesticidal efficacy of their own): solvents such as alcohols and 
hydrocarbons; surfactants such as polyoxyethylene polymers and fatty 
acids; carriers such as clay and diatomaceous earth; thickeners such as 
carrageenan and modified cellulose; wetting, spreading, and dispersing 
agents; propellants in aerosol dispensers; microencapsulating agents; 
and emulsifiers. The term ``inert'' is not intended to imply 
nontoxicity; the ingredient may or may not be chemically active. 
Generally, EPA has exempted inert ingredients from the requirement of a 
tolerance based on the low toxicity of the individual inert 
ingredients.

IV. Aggregate Risk Assessment and Determination of Safety

    Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an 
exemption from the requirement for a tolerance (the legal limit for a 
pesticide chemical residue in or on a food) only if EPA determines that 
the tolerance is ``safe.'' Section 408(c)(2)(A)(ii) of FFDCA defines 
``safe'' to mean that ``there is a reasonable certainty that no harm 
will result from aggregate exposure to the pesticide chemical residue, 
including all anticipated dietary exposures and all other exposures for 
which there is reliable information.'' This includes exposure through 
drinking water and in residential settings but does not include 
occupational exposure. When making a safety determination for an 
exemption for the requirement of a tolerance FFDCA section 408(c)(2)(B) 
directs EPA to consider the considerations in section 408(b)(2)(C) and 
(D). Section 408(b)(2)(C) of FFDCA requires EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance and to ``ensure that there 
is a reasonable certainty that no harm will result to infants and 
children from aggregate exposure to the pesticide chemical residue . . 
. .'' Section 408(b)(2)(D) lists other factors for EPA consideration 
making safety determinations, e.g., the validity, completeness, and 
reliability of available data, nature of toxic effects, available 
information concerning the cumulative effects of the pesticide chemical 
and other substances with a common mechanism of toxicity, and available 
information concerning aggregate exposure levels to the pesticide 
chemical and other related substances, among others.
    EPA establishes exemptions from the requirement of a tolerance only 
in those cases where it can be clearly demonstrated that the risks from 
aggregate exposure to pesticide chemical residues under reasonably 
foreseeable circumstances will pose no harm to human health. In order 
to determine the risks from aggregate exposure to pesticide inert 
ingredients, the Agency considers the toxicity of the inert in 
conjunction with possible exposure to residues of the inert ingredient 
through food, drinking water, and through other exposures that occur as 
a result of pesticide use in residential settings. If EPA is able to 
determine that a tolerance is not necessary to ensure that there is a 
reasonable certainty that no harm will result from aggregate exposure 
to the inert ingredient, an exemption from the requirement of a 
tolerance may be established.
    Consistent with FFDCA section 408(c)(2)(A), and the factors 
specified in FFDCA section 408(c)(2)(B), EPA has reviewed the available 
scientific data and other relevant information in support of this 
action. EPA has sufficient data to assess the hazards of and to make a 
determination on aggregate exposure for acetic acid, 2-ethylhexyl ester 
including exposure resulting from the exemption established by this 
action. EPA's assessment of exposures and risks associated with acetic 
acid, 2-ethylhexyl ester follows.

A. Toxicological Profile

    EPA has evaluated the available toxicity data and considered their 
validity, completeness, and reliability as well as the relationship of 
the results of the studies to human risk. EPA has also considered 
available information concerning the variability of the sensitivities 
of major identifiable subgroups of consumers, including infants and 
children. Specific information on the studies received and the nature 
of the adverse effects caused by acetic acid, 2-ethylhexyl ester as 
well as the no-observed-adverse-effect-level (NOAEL) and the lowest-
observed-adverse-effect-level (LOAEL) from the toxicity studies are 
discussed in this unit.
    The toxicological database of acetic acid, 2-ethylhexyl ester is 
supported by data on the oxy-alkyl acetates and 2-

[[Page 67373]]

ethyl-1-hexanol. EPA has determined that it is appropriate to bridge 
the data due to similarities in the manufacturing processes, functional 
groups/structure, composition, and physical/chemical properties of 
these chemicals.
    Based on the results of surrogate data, acetic acid, 2-ethylhexyl 
ester is expected to exhibit low levels of acute toxicity via the oral, 
dermal, and inhalation routes of exposure. In the rat, the oral 
LD50 is 5,000 mg/kg, the dermal LD50 is 3,160 mg/
kg and the inhalation LC is >1,100 ppm. Studies showed slight/moderate 
skin and eye irritation and no protein binding alerts for skin 
sensitization were found.
    Two oral subchronic studies, a subchronic inhalation study, and a 
developmental study conducted using surrogate chemicals were evaluated. 
In a 28-day gavage study in rats with oxo-hexyl acetate, no effects 
were seen up to the limit dose of 1,000 mg/kg/day. A 90-day study 
gavage study in rats with oxo-octyl acetate showed kidney effects (mild 
tubular nephropathy) in high-dose males only at the LOAEL of 1,000 mg/
kg/day. The 90-day inhalation study in rats with 2-ethyl-1-hexanol 
showed no effects up to the highest dose tested (638.4 mg/m\3\).
    In a developmental toxicity study, oxo-octyl acetate was 
administered by gavage to pregnant female rats. Decreased maternal body 
weight and food consumption, as well as fetal vertebral malformations, 
were noted at 1,000 mg/kg/day only. Two animals in the high dose group 
died, no etiology was given. The developmental and maternal systemic 
NOAEL was 500 mg/kg/day, and the LOAEL was 1,000 mg/kg/day.
    No evidence of neurotoxicity or immunotoxicity was reported. 
Furthermore, concern for carcinogenicity is low based on negative 
results in mutagenicity studies, and the lack of structural alerts for 
carcinogenicity.

B. Toxicological Points of Departure/Levels of Concern

    Once a pesticide's toxicological profile is determined, EPA 
identifies toxicological points of departure (POD) and levels of 
concern to use in evaluating the risk posed by human exposure to the 
pesticide. For hazards that have a threshold below which there is no 
appreciable risk, the toxicological POD is used as the basis for 
derivation of reference values for risk assessment. PODs are developed 
based on a careful analysis of the doses in each toxicological study to 
determine the dose at which no adverse effects are observed (the NOAEL) 
and the lowest dose at which adverse effects of concern are identified 
(the LOAEL). Uncertainty/safety factors are used in conjunction with 
the POD to calculate a safe exposure level--generally referred to as a 
population-adjusted dose (PAD) or a reference dose (RfD)--and a safe 
margin of exposure (MOE). For non-threshold risks, the Agency assumes 
that any amount of exposure will lead to some degree of risk. Thus, the 
Agency estimates risk in terms of the probability of an occurrence of 
the adverse effect expected in a lifetime. For more information on the 
general principles EPA uses in risk characterization and a complete 
description of the risk assessment process, see https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/overview-risk-assessment-pesticide-program.
    The hazard profile of acetic acid, 2-ethylhexyl ester is adequately 
defined. Overall, acetic acid, 2-ethylhexyl ester is of low acute, 
subchronic, and developmental toxicity. No systemic toxicity was 
observed at doses that are relevant for risk assessment (i.e., doses 
below 1,000 mg/kg/day). Since signs of toxicity were not observed below 
1,000 mg/kg/day, no toxicological endpoints of concern or PODs were 
identified. Therefore, a qualitative risk assessment for acetic acid, 
2-ethylhexyl ester can be performed.

C. Exposure Assessment

    1. Dietary exposure from food and feed uses. In evaluating dietary 
exposure to acetic acid, 2-ethylhexyl ester, EPA considered exposure 
under the proposed exemption from the requirement of a tolerance. EPA 
assessed dietary exposures from acetic acid, 2-ethylhexyl ester in food 
as follows:
    Dietary exposure (food and drinking water) to acetic acid, 2-
ethylhexyl ester may occur following ingestion of foods with residues 
from their use in accordance with this exemption. However, a 
quantitative dietary exposure assessment was not conducted since a 
toxicological endpoint for risk assessment was not identified.
    2. From non-dietary exposure. The term ``residential exposure'' is 
used in this document to refer to non-occupational, non-dietary 
exposure (e.g., textiles (clothing and diapers), carpets, swimming 
pools, and hard surface disinfection on walls, floors, tables). Acetic 
acid, 2-ethylhexyl ester may be present in pesticide and non-pesticide 
products that may be used in and around the home. However, a 
quantitative residential exposure assessment was not conducted since a 
toxicological endpoint for risk assessment was not identified.
    3. Cumulative effects from substances with a common mechanism of 
toxicity. Section 408(b)(2)(D)(v) of FFDCA requires that, when 
considering whether to establish, modify, or revoke a tolerance, the 
Agency consider ``available information'' concerning the cumulative 
effects of a particular pesticide's residues and ``other substances 
that have a common mechanism of toxicity.''
    Based on the lack of toxicity below the limit dose, EPA has not 
found acetic acid, 2-ethylhexyl ester to share a common mechanism of 
toxicity with any other substances, and acetic acid, 2-ethylhexyl ester 
does not appear to produce a toxic metabolite produced by other 
substances. For the purposes of this tolerance exemption, therefore, 
EPA has assumed that acetic acid, 2-ethylhexyl ester does not have a 
common mechanism of toxicity with other substances. For information 
regarding EPA's efforts to determine which chemicals have a common 
mechanism of toxicity and to evaluate the cumulative effects of such 
chemicals, see EPA's website at https://www.epa.gov/pesticide-science-and-assessing-pesticide-risks/cumulative-assessment-risk-pesticides.

D. Additional Safety Factor for the Protection of Infants and Children

    Section 408(b)(2)(C) of FFDCA provides that EPA shall apply an 
additional tenfold (10X) margin of safety for infants and children in 
the case of threshold effects to account for prenatal and postnatal 
toxicity and the completeness of the database on toxicity and exposure 
unless EPA determines based on reliable data that a different margin of 
safety will be safe for infants and children. This additional margin of 
safety is commonly referred to as the Food Quality Protection Act 
(FQPA) Safety Factor (SF). In applying this provision, EPA either 
retains the default value of 10X, or uses a different additional safety 
factor when reliable data available to EPA support the choice of a 
different factor.
    Because there were no adverse effects below 1,000 mg/kg/day 
associated with acetic acid, 2-ethylhexyl ester, EPA conducted a 
qualitative assessment. As part of that assessment, the Agency did not 
use safety factors for assessing risk, and no additional safety factor 
is needed for assessing risk to infants and children. Based on an 
assessment of acetic acid, 2-ethylhexyl ester, EPA has concluded that 
there are no toxicological endpoints of concern for

[[Page 67374]]

the U.S. population, including infants and children.

E. Aggregate Risks and Determination of Safety

    Because no toxicological endpoints of concern were identified below 
the limit dose, EPA concludes that there is a reasonable certainty that 
no harm will result to the general population, or to infants and 
children from aggregate exposure to acetic acid, 2-ethylhexyl ester 
residues.

V. Analytical Enforcement Methodology

    An analytical method is not required for enforcement purposes since 
the Agency is not establishing a numerical tolerance for residues of 
acetic acid, 2-ethylhexyl ester in or on any food commodities. EPA is 
establishing a limitation on the amount of acetic acid, 2-ethylhexyl 
ester that may be used in pesticide formulations applied pre-harvest. 
This limitation will be enforced through the pesticide registration 
process under the Federal Insecticide, Fungicide, and Rodenticide Act 
(``FIFRA''), 7 U.S.C. 136 et seq. EPA will not register any pesticide 
formulation for food use that exceeds 50% acetic acid, 2-ethylhexyl 
ester in the final pesticide formulation.

VI. Conclusions

    Therefore, an exemption from the requirement of a tolerance is 
established for residues of acetic acid, 2-ethylhexyl ester (CAS Reg. 
No. 103-09-3) when used as an inert ingredient (solvent/co-solvent) at 
a maximum of 50% by weight in pesticide formulations applied to growing 
crops only under 40 CFR 180.920.

VII. Statutory and Executive Order Reviews

    This action establishes an exemption from the requirement of a 
tolerance under FFDCA section 408(d) in response to a petition 
submitted to the Agency. The Office of Management and Budget (OMB) has 
exempted these types of actions from review under Executive Order 
12866, entitled ``Regulatory Planning and Review'' (58 FR 51735, 
October 4, 1993). Because this action has been exempted from review 
under Executive Order 12866, this action is not subject to Executive 
Order 13211, entitled ``Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 
28355, May 22, 2001) or Executive Order 13045, entitled ``Protection of 
Children from Environmental Health Risks and Safety Risks'' (62 FR 
19885, April 23, 1997). This action does not contain any information 
collections subject to OMB approval under the Paperwork Reduction Act 
(PRA) (44 U.S.C. 3501 et seq.), nor does it require any special 
considerations under Executive Order 12898, entitled ``Federal Actions 
to Address Environmental Justice in Minority Populations and Low-Income 
Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), such as the exemption in this 
final rule, do not require the issuance of a proposed rule, the 
requirements of the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et 
seq.), do not apply.
    This action directly regulates growers, food processors, food 
handlers, and food retailers, not States or Tribes, nor does this 
action alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, the Agency has determined that 
this action will not have a substantial direct effect on States or 
Tribal Governments, on the relationship between the National Government 
and the States or Tribal Governments, or on the distribution of power 
and responsibilities among the various levels of government or between 
the Federal Government and Indian Tribes. Thus, the Agency has 
determined that Executive Order 13132, entitled ``Federalism'' (64 FR 
43255, August 10, 1999) and Executive Order 13175, entitled 
``Consultation and Coordination with Indian Tribal Governments'' (65 FR 
67249, November 9, 2000) do not apply to this action. In addition, this 
action does not impose any enforceable duty or contain any unfunded 
mandate as described under Title II of the Unfunded Mandates Reform Act 
(UMRA) (2 U.S.C. 1501 et seq.).
    This action does not involve any technical standards that would 
require Agency consideration of voluntary consensus standards pursuant 
to section 12(d) of the National Technology Transfer and Advancement 
Act (NTTAA) (15 U.S.C. 272 note).

VIII. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
EPA will submit a report containing this rule and other required 
information to the U.S. Senate, the U.S. House of Representatives, and 
the Comptroller General of the United States prior to publication of 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
